Radioulunar Ligament Tear
Clearwater, Tampa, St Petersburg, Florida
With a radioulunar ligament tear, there can be instability in the wrist, where the ends of the radius and ulnar bones meet. This would lead to wrist pain.
On both the volar (the palm side) and dorsal (back of the hand) aspect of the wrist, run radioulnar ligaments that connect the distal aspects of the long bones of the forearm where they connect with the carpal bones of the wrist. Both ligaments on the volar and dorsal surface connect with the triangular fibrocartilage complex (TFCC).
Traumatic injuries can cause disruption of the dorsal radioulunar ligament of the volar radioulnar ligament. This can be confused with other sources of wrist pain (especially pain in close proximity to the TFCC), making an accurate diagnosis somewhat difficult based only on physical exam. Magnetic resonance imaging (MRI) is usually necessary to differentiate the diagnosis, along with standard x-rays, which would show degenerative changes or traumatic fractures.
If a radioulnar ligament is completely disrupted, there can be instability at the wrist. This can be seen on both x-rays and MRI as a displacement between the distal aspect of the radius and the ulnar. As this again is in close proximity to many other problematic areas that may cause chronic wrist pain, a skilled clinician must be adept in using a clinical exam history and appropriate imaging studies to diagnose this.
If the wrist is still stable, then conservative care is advised. A splint worn for four to six weeks will immobilize the wrist, allowing it to heal. Anti-inflammatory drugs and physical therapy may also be prescribed. A corticosteroid injection may also help.
If the wrist is unstable, a cast on the wrist and forearm or surgery may be appropriate.
An alternative treatment for a radioulunar ligament tear would be an injection of platelet-rich plasma (PRP) and/or stem cell therapy. Both of these cutting-edge technologies may accelerate the healing of these ligaments. Platelet-Rich Plasma (PRP) therapy captures the healing growth factors that are in a person’s own blood. By injecting the PRP into the damaged area of the wrist, it may help heal the affected area and diminish pain. In addition, there are indications for platelet-rich plasma in healing a variety of conditions, in much the same way that stem cells may help regenerate different types of tissues.
